Low-Voltage, CMOS Analog Multiplexers
The MAX398/MAX399 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance (less
than 100Ω), which is matched to within 6Ω between
channels and remains flat over the specified analog signal range (11Ω max). They also offer low leakage over
temperature (NO off-leakage current less than 2.5nA at
+85°C) and fast switching speeds (transition time less
than 250ns). The MAX398 is an 8-channel device, and
the MAX399 is a dual 4-channel device.
The MAX398/MAX399 are fabricated with Maxim’s lowvoltage silicon-gate process. Design improvements yield
extremely low charge injection (less than 5pC) and guarantee electrostatic discharge protection (ESD) greater
than 2000V.
These muxes operate with a single +3V to +15V supply or
bipolar ±3V to ±8V supplies, while retaining CMOS-logic
input compatibility and fast switching. CMOS inputs provide reduced input loading. The MAX398/MAX399 are
pin compatible with the industry-standard DG408,
DG409, DG508A, and DG509A. Applications
